Obanai is a short young man. He has shoulder-length black hair with long bangs. Obanai was born with heterochromia, so his eyes are different: the color of his right eye is yellow, and the left one is turquoise. He is partially blind and can barely see with his right eye. When he was twelve, his mouth was cut down to his ears, resulting in a scar that he hides under a mask of bandages. Obanai is 21 years old and is 162 centimeters tall.
